Needleless Systems/Protected Needles

Measurement Systems

 

 

Volume and Weight Equivalents

Basic principles of math

 

 

 

 

 

 

 

 

Converting between systems of measurement

 

May need 2 steps

Drugs measured in Units

 

5,000U X 1ml = 20,000U

Give = 1 or .25 ml 4

 

100 x = 40

x = 0.4 ml

Drugs provided in powder form

 

Add for U/ml 18 ml 250,000 8 ml 500,000 3 ml 1,000,000

(sterile water,NaCl)

You want to give 500,000U per dose.

 

 

IV fluids

medications to be added

to continuous infusion

to intermittent infusion

(IVPB)

as bolus dose

Calculating milliliters per hour

Calculating Drops per Minute

= 31.25 gtt/min

Round to 31 gtt/min

Common IV Drop Factors

 

Rx: Kefzol 1 g IVPB q 6 h

(Mix in 50 ml D5W. Infuse over 20 min.)

Drop factor is 20 gtt/ml

Kefzol supplied as 500mg/ml.

500 mg = 1g

1 ml x ml

500 mg = 1000 mg

1 ml x ml

500 x = 1000

x = ml

 

 

 

 

 

50 ml X 20 (drop factor) = 20 (time in minutes)

1000 = 20

Run at 50 gtts/min

Tips from Errickson & Todd

e.g. 60 mg = 90 mg (60mg:1tab::90mg:x tabs) 1 tab x tabs

Names of drugs

USP, NF

Hydrodiuril

Classifications of Drugs

According to:

Kinds of Drug Actions

therapeutic should outweigh side effect

Kinds of Drug Actions

Adverse effects (FDA MEDWATCH)

Iatrogenic disease

(e.g. elderly)

anaphylactic reaction - sudden, life-threatening

Drug Interactions

Combined effect of 2 or more drugs alters effect of one or both:

Demerol and Phenergan

Drug Standards

To predict effect based on consistency,

uniform quality
